I would like to get an invite to mywallop.com

"In Wallop, you can share photos, blog, and interact with your
friends. Wallop is a research project that explores how people share
media and build conversations in the context of social networks. We
are currently conducting a small, real world trial of Wallop with
small friendship groups. Therefore, membership in Wallop
http://mywallop.com is limited to study participants until the trial
is over."
